Biology Chapter 1

1. and Heredity DNA carries the information in all living things and is passed on to offspring through a process called heredity
3. Living things maintain a stable internal environment
6. well-tested explanation that unifies a broad range of observations that has been throughly tested
10. Experiment an experiment in which only one variable is manipulated at a time
12. Variable the variable that is measured in an experiment, the outcome factor; the variable that may change in response to manipulations of the independent variable
13. variable The experimental factor that is manipulated; the variable whose effect is being studied.
15. and Diversity of Life All living things have basic similarities (carbon-based, DNA) even though they are different
18. and Function Living things have different structures (body parts) to help them achieve certain functions.
20. process of noticing and describing events or processes in a careful, orderly way
21. an organized way of gathering and analyzing evidence about the natural world.

2. in Nature All living things are connected and depend on one another
4. Basis of Life Living things are made up of cells
5. as a way of knowing Scientists use explanations, observations and questions to explain the natural world
7. Variable that is measured
8. a proposed scientific explanation for a set of observations in ways that support or reject it
9. and Energy Living things obtain and consume matter for energy.
11. information gathered from experimental observations
13. logical interpretation based on prior knowledge and experience
14. Groups of living things evolve or change over time
16. Development and Reproduction Living things get bigger in size, mature (develop) and produce offspring
17. Group in an experiment, the group that is not exposed to the treatment; contrasts with the experimental group and serves as a comparison for evaluating the effect of the treatment.
19. a partiality that prevents objective consideration of an issue or situation
